in thread Blinking a row

The \r carriage return is useful for incrementing counters but can also do blink - If you have to! A reasonable purpose would be say if the nuclear reactor powering you computer is in danger of a China Syndrome meltdown due to problems with the heavy water supply from your municipal authority....

do{ print 0==$a++%2 ?"Core Meltdown!\r" : " \r"; sleep 1} + while 1;

cheers
